This invention relates to improvements in fire fighting equipment for storage tanks, and more particularly relates to an improved portable foam applicator. v v I The invention will be fully understood from the following description taken in connection with the accompanying dra in which latter- Fig. 1 is a side elevational view of the device assembled at the side of a storage tank.

Fig. 2 is a top plan view of the mixing chamber.

Fig. 3 is a detailed side elevational view of the mixing chamber with parts broken away.

Referring particularly to the drawings, the foam applicator is described as applied to an oil tank 1, the mixing chamber being partially elevated up the tank sometimes catch on fire and the portable foam applicator functions as an eilicient means for rapidly applying fire extinguishing foam to the upper surface of the burning body of oil. Referfor example of 1%" pipe bent into a hooked form 3 at one end. The handle endof the pole is provided with hand grips4. A handle 5 extends at right angles to the handle end of the pole. The handle 5 is providedwith a socket member 6 which is welded to the handle and is adapted to receive the handle end of the pole 2. The socket member 6 and the base of the pole are provided with aligned slots adapted to receive a suitable bolt '7 to lock the connection there-between.

Light hand poles 10 and 11 with their extensions.

10 and 11' are connected to the portable pole 2 part way up the portable pole. The connection is.

formed by means of a sliding collar 12 which in service is rigidly secured to the pole 2 at some height depending upon the height of the tank. The collar 12 carries projecting ears 13 which are connected by suitable rings 14 to the hand poles l 10 and 11. The hand poles 10 and 11 function to 46 assist in raising the pipe pole 2 to a vertical posiend 3 to hook over the top angle of the tank 1.

A mixing chamber 20 is then hoisted into position to deliver foam or the like from its discharge end 21 over the edge of the tank 1. The mixing chamber is hoisted by means of the pulley blocks 22 and 23 and the tackle 24 constituting a block and fall. The tackle 24 is preferably made of steel cable and the pulley blocks 22 and 23 are 65 preferably made of steel. The pulley block 22 is Fig. 5 is a perspective view of the apparatus in' the side of the tank in Fig. 1. The oil contents of ence numeral 2 designates a portable pole made tion: elevated sufficiently to enable the hooked (Cl. 16H) secured to the mixing chamber 20 by means of a flat iron 26* having an eye 2'1suitably secured to the mixing chamber. The pulley block 231s secured to the main pulley 2 by means of a rill! 30. The mixing chamber is provided with inlet lines 31 and 32. Prior to raising the mixing chamber, hose lines 31'32' see Fig. 5, are connected to the inlet lines 31 and 32. The hose lines lead from a suitable source of foam making material, not shown. The material is mixed together in the mixing chamber and delivered as foam through the downwardly facing delivery end 21.

By the apparatus described, the foam applicator can be speedily and manually positioned to deliver fire extinguishing foam directly upon the 7 surface of the burning oil in a tank. The apparatus can be transported manually, hastily through narrow places over lines, concrete walls and the like to the tankcontaining the burning contents.

Various changes may be made within the scope 7 of the appended claims in which it is desired to claim all novelty inherent in the invention as broadly-as the prior art permits.

I claim:

1. A foam applicator for a tank the contents of which are burning, comprising a portable pole of a length substantially equal to the height of the tank and having a hooked end adapted to be hooked over the top edge of the tank, a mixing chamber of lesser length than the pole and 86 having a delivery end, and means connected to the hooked end of the portable pole and to the chamber whereby the delivery end of. the chamber can be hoisted from the ground to a position over the top edge of the tank.

2. A foam applicator for a tank the contents of which are burning, comprising a mixing chamber, a portable pole of a length substantially equal to the height of the tank having a hooked end adapted to be hooked over the top edge of the tank, and a hoist connected to the hooked end of thepole and to the chamber whereby the delivery end of the chamber can be hoisted from thgk ground to a position over the top edge of the ta 3. A foam applicator for a tank the contents of which are burning, comprising a mixing chamber, a portable pole of greater length than the mixing chamber and of a length substantially I equal to the height of the tank and having a hooked end adapted to be hooked over the top edge of the tank, hand poles of lesser length than the portable pole connected to an intermediate portion of the portable pole, and a hoist connected to the hooked end of the portable pole and to the chamber whereby the delivery end of the chamber can be hoisted from the ground to a position over the top edge of the tank.

4. In a hoisting device for the mixing cham-- ber of a foam applicator for a tank the contents of which are burning, a portable pole of a length substantially equal to the height of the tank and having a hooked end adapted to be hooked over the top edge of the tank, and means connected to the hooked end of the pole and adapted to be connected to the mixing chamber whereby the delivery end of the chamber can be hoisted from the ground to a position over the top edge of the tank.

5. In a hoisting device for the mixing chamber of a foam applicator for a tank the contents of which are burning, a portable pole of a. length substantially equal to the height of the tank and having a hooked end adapted to be hooked over the top edge of the tank, hand poles connected to an intermediate portion of the portable pole, and means connected to the hooked end of the pole and adapted to be connected to the chamber whereby the delivery end of the chamber can be hoisted over the top edge of the tank.

6. In a hoisting device for the mixing chamber of a foam applicator for a tank the contents of which are burning, a portable pole of a length substantially equal to the height of the tank and having a hooked end adapted to be hooked over the top edge of the tank, jointed hand poles connected to an intermediate portion of the portable pole, and means connected to the hooked end of the pole and adapted to be connected to the chamber whereby the delivery end of the chamber can be hoisted over the top edge of the tank.

, 7. In a hoisting device for the mixing chamber of a foam applicator for a tank the contents cf whichare burning, a portable pole of a length substantially equal to the height 01 the tank and having a hooked end adapted to be hooked over the top edge of the tank, hand poles connected to an intermediate portion of the portable pole, and a steel block and fall connected to the hooked end 01' the pole and adapted to be connected to the chamber, whereby the delivery end of the chamber can be hoisted over the top edge of the tank.
